IARU Reg. I CW Field Day was last weekend with few stations having RFI and 
using manual keying with VOX.
I'd doubt whether letter J means shorted 1 or number 2 with first dot lost due 
to the late VOX/semi-BK action.

Morse coded numbers have regular 5 elements structure but we don't need all of 
them, just the exact point of dot to dash transition.  If I am expecting 
numbers, A is enough for 1, U for 2, V for 3, E for 5, G for 7, N for 9 and T 
equals 0.  Numbers 4, 6 and 8 can't be reasonably abbreviated.  

Fortunately only NEAT usage makes sense for significantly reduced timing.  We 
are supposed to be smart decoders, not automated ones.  However, machine 
sending is prefered as it reduces human transmission errors!
